DNA Identification in Breast Milk from Mexican Women with Chagas Disease.

(1) Background: Chagas disease is a public health problem affecting nearly 2 million women of reproductive age in Latin America. From these, 4-8% can transmit the infection to the foetus through the vertical route, whereas horizontal transmission through milk during breastfeeding remains controversial. Therefore, the presence of () DNA in the milk of women seropositive for Chagas disease was analysed to determine whether a relationship with the infection of their children can exist.

Maternal fetal transmission of Trypanosoma cruzi: a problem of public health little studied in Mexico.

The first case of neonatal Chagas was reported in Mexico in 1998, but there have been no studies since then. Therefore, we investigated the rates of congenital infection of Trypanosoma cruzi by examining the seroprevalence among 1448 pregnant women in Oaxaca, Jalisco and Mexico City. We performed ELISAs to screen for recombinant and total antigens in mothers, and examined the frequency of congenital T.
